An MRI machine is a medical imaging device that uses strong magnets and radio waves to create detailed images of the inside of the body. It is particularly useful for examining soft tissues, such as the brain, muscles, and organs, helping doctors diagnose various conditions. During an MRI scan, the patient lies on a table that slides into a large, tube-shaped magnet. The procedure is painless and typically lasts between 15 to 90 minutes. Patients may hear loud tapping or thumping noises during the scan, but they can communicate with the technician throughout the process.
